MR Tuning USA Automotive - Miami, Florida

Do NOT go there. I went to tune my car because it was presenting stalling issues. First bad sign was that I was not told any price until right before mounting it on the Dyno. I also got an appointment time and was not attended until an hour later.
Once they started mounting it, the owner gave the car to someone who was learning.
After 2 hours it was supposedly “complete”.
Wasted $650 for nothing!
Now my car keeps stalling but my Speedometer is 10 MPH ahead now. And let’s not talk about my MPG now, around 100 miles on a tank of 22 gallons!
When I went back to get that fixed, they proceeded to blame on my O2 sensors and camshafts, and of course wanted me to pay more to fix the Speedometer when they messed it up at first.

Trust me don’t go there if you like your car and your money!

Update: Took a little while but he emailed me the tune which I’m grateful for. Now the car is running as the tune is supposed to be (minus the vacuum leak I need to take care of ?). I’ve read mixed reviews about the service here but I give him a big kudos for not password locking the file like many other unscrupulous tuners do. It’s very helpful because I can turn on or off code messages and most importantly, decide the coolant fan’s operation. I don’t touch the tune, that would invalidate what I paid for.

Great guy. But the way he tunes is unconventional. When he dyno tunes the car he’s up shifting through the gears at WOT. I’ve never experienced this before. Pretty much every time I’ve dynoed my car, the tuner always uses a 1:1 gear and ramps it up but not him. He mistakenly assumed that a tune could be downloaded directly from the ECU which I first started to believe him until I found out from company that supplies the tuning software, that it isn’t so. Essentially, I paid over $400 for a car without the tune he gave me. I’m in communication with him to at least email me the tune so I can reflash my ECU since he said he still had the file when I spoke to him on the phone. Once this has been resolved I’ll update the star rating.

I did a trade in with them in January. I traded a 2001 Corvette C5 for an Acura RSX. It turned out the Acura had miles rolled back and so I had no choice but to negotiate to have another car with them. I chose a prelude from their shop that just required a JDM F20B swap. I said 'ok' and did the trade for some extra cash on top. After two weeks using it the car began to leak oil and 2 days ago the timing belt exploded while I was on the palmetto going northbound. If you have ever had that happen to you I can guarantee you will traumatized. I had to pay for a tow truck and sit in traffic for 2 hours. The engine is trashed and doesn't start anymore. Now I have to buy a different car. I repeat do not work with them. They have been extremely unprofessional and are a big scam. Who doesn't add a new timing belt to a car with so many miles? On top of that, they didn't event let me know. I wasted lots of time and money already with them.

They destroyed my hood installing hood pins, and also my radio stopped working when I picked up the car. Michael the owner now says that I need to proof the radio was working and also to pay $300 to get my hood fixed
Trash people, trash quality

Best tuner in town, I took my Camaro there to be tuned after another tuner did a lousy job. He took his time and not only fixed the problem but also did an amazing job. He is the kinda guy that takes his work serious and will get it right no matter how long it takes. I highly recommend you check him out.

This place is great the owners are extremely friendly they will work with you in any problem you'll encounter. Most of my friends and family come here for auto work or just maintenance I can vouch they won't do you wrong. This one time I owned a Genesis coupe on a Sunday late afternoon both my rear tires got a flat, I called Michael the owner and explain the situation. I told him it was being towed to the shop on his day off he got someone to go open the gates so I may store the car for further work the next day. Another time I brought my Jeep liberty CRD for a timing belt and as a courtesy he also replaced the windshield wipers free of charge because I was a loyal customer. If you need work done give this place a shot.

Great group of guys, great service. Knew exactly what was wrong with my car, told me he'll have it back to peek performance in two days, and he did. Thanks, Mike.
